US Harbors with natural water depths for today's or tomorrow's vessels are anomalies.
Seasonal Constraints on projects are driven by resource & habitat impact concerns during seasonal activities.
In many areas data on impact risks to lifestages & habitats is limited but constraints impact ≈ 85 % of projects.
1.Presence/absence data are available.
2. Habitat-related density data are available.
3. Habitat-related growth, reproduction, or survival rate are available.
LITTLE DATA, LOTS OF UNCERTAINTY
Operational restrictions have problems:
► Decant or precipitate
►Bite the Bullet: impact a single year of area's resource
